A heat pipe is a copper tube with a vacuum inside it. In the vacuum is water, which since there is no Atmospheric pressure, ie air, the water boils. Steam has a ton of thermal properties, among them the ability to hold tremendous amounts of heat... then moving them to the heat sinks.

Remember, putting your hand in 100c water is better than putting your hand in 100c steam

Hey Psyduck: do you know how many watts of heat the celeron pumps out? a 56watt on 12v seems a bit... not enough?

Geez - what impressive pictures of the xeon. I guess you live with the machine, ah :-) I am a novice, when compared to the extremes all of you cooling fanatics :-) I have a tower case, which I am planning to add better cooling. I want your comments on the below. I can expect ambient temperatures here in SF bay area to get as hot as 95 deg. Farenheit. (about 35 C) in summer. My K6-3 can handle upto 65 C. What do u think about using 5 fans , as below, all powered from my 300W supply.

1. 120mm TOYO fan (the only big fan at Frys), located at bottom front, with intake of about 75 CFM !! I expect the intake to be reduced by my airfilter to about 50 CFM.

2. 50mm Cooler Master fan, used as intake, on the rear of the case, in line with where the CPU is located - I read that AMD noticed significant temp. reductions with addition of a fan in this location.

3. CyberCooler (40mm) and heatsink on top of my overclocked K6-3 (333@427, 2.4v) - this CPU performs better than many K6-2 or Celeron running at 500 because of the built it cache.

4. A tiny fan located near CPU area that is used to push the hot air from CPU fan upwards, in the vertical tower case.

5. A 80mm exhaust fan that is rigged in a hole I created at the top surface of the tower case, to pump out hot air collecting at top of towercase.

6. 60mm exhaust fan in the 300W power supply.

Is this a overkill, with that 75 CFM intake ? Should I be spending money on a peltier instead ? I am a little nervous about peltiers, as I am not that experienced with overclocking and besides, I don't want to buy a different size peltier, for $30 a pop each, everytime I change mobo-CPU combo.

Thanks for all replies.
